For example, PVC and PU leather are generally called artificial leather or imitation leather. PVC and PU are both polyvinyl chloride (one of the plastics), but the manufacturing process of these two products is different.

PVC leather in the process of manufacturing plastic particles melt mixing into a paste, in accordance with the provisions, the thickness of the uniform coating on T/C knitted fabric bottom base, and then into the foam foaming furnace, make its have can adapt to produce all kinds of different products and different requirements of flexibility, while out for surface treatment (dyeing, embossing, extinction, grinding surface polishing, burr, etc., mainly in accordance with the specific product requirements for).

PU leather on the manufacturing process are more complex than PVC leather, due to the PU backing is tensile strength good canvas PU material, in addition to the coating on the top of the base cloth, also of knitted fabrics can be contained in the middle, the watch is not exactly the existence of the cloth. The physical properties of PU leather are better than that of PVC leather, with better resistance to torsion, softness, tensile strength and breathability (PVC is not available). The pattern of PVC leather is made by hot pressing of steel pattern roller. The pattern of PU leather is to use a kind of decorative paper to press on the surface of semi-finished leather, wait for cooling down, then separate the paper leather and do surface treatment. The price of PU leather is more than double that of PVC leather, and the price of some PU leather with special requirements is 2-3 times higher than that of PVC leather. The pattern paper needed for PU leather can only be used 4-5 times, which will be scrapped immediately. The usage period of decorative roller is long, so the cost of PU leather is higher than that of PVC leather.


There are also some differences in the scope of application between the two materials. In footwear, PVC leather is used for lining or non-weight parts, or for making children's shoes. PU leather can be applied to the fabric of shoes or the parts that bear weight. In the aspect of bag bag, PVC leather is more suitable. This is because the items in the bag do not emit heat, unlike the feet in the shoes. You don't have to bear your own weight.

The difference between PU and PVC is relatively easy. From the side corner, the base cloth of PU is much thicker than that of PVC. PVC has a harder feel. You can also burn it with fire. PU tastes much lighter than PVC.
